Stromboli volcano (Aeolian Islands, Italy) has two types of magma: volatile-rich, aphyric magma (LP) that produces pumices and volatile-poor, highly porphyritic magma (HP) that produces scoria. This work studies how changes of magma properties affect the bubble formation and growth, and the dynamics of volcano eruptions. The first part of this work is a study of bubble formation and growth in crystal-free Stromboli basalts. Using X-ray microtomography (µCT) I studied the 3-D bubble sizes and distributions, determined the permeability with lattice-Boltzmann simulations and laboratory measurements, investigated the factors that control the occurrence of Darcian and non-Darcian flow, and delineated the Darcian and non-Darcian flow regimes in t...
